Birds of America
By John James Audubon, F. R. SS. L. & E.
SYLVICOLA AGILIS, Wils.
PLATE XCIX.--MALE AND FEMALE.
I procured the pair represented in the plate, on a fine evening, nearly at
sun-set, at the end of August, on the banks of the Delaware river, in New
Jersey, a few miles below Camden. When I first observed them, they were bopping
and skipping from one low bush to another, and among the tall reeds of the
marsh, emitting an often-repeated tweet at every move. They were chasing a
species of spider which runs nimbly over the water, and which they caught by
gliding over it, as a Swallow does when drinking. I followed them for about a
hundred yards, when, watching a fair opportunity, I shot both at once. The
weather was exceedingly sultry; and although I outlined both by candle-light
that evening, and finished the drawing of them next morning by breakfast time,
they had at that early hour become putrid, so that their skins could not be
preserved. On opening them I counted upwards of fifty of the spiders mentioned
above, but found no appearance of any other food. The sexual distinction was
very apparent, and the brace proved a pair. They were not in the least shy, and
in fact seemed to take very little notice of me, although at times I was quite
close to them. These being the only individuals I ever met with, I am of course
unable to say where the species breeds, or what are its migrations.
The plant on which they are placed grew abundantly on the spot where I
procured them; and as they had just alighted on it when I shot them, it being
moreover a handsome species, I thought it best to attach it to them.
WILSON's account of this bird is as follows: "This is a new species, first
discovered in the State of Connecticut, and twice since met with in the
neighbourhood of Philadelphia. The different specimens I have shot correspond
very nearly in their markings; two of these were males, and the other
undetermined, but conjectured also to be a male. It was found in every case
among low thickets, but seemed more than commonly active, not remaining for a
moment in the same position.
"Length five inches and three quarters; extent eight inches; whole upper
parts a rich yellow-olive; wings dusky brown, edged with olive; throat dirty
white or pale ash; upper part of the breast dull greenish-yellow; rest of the
lower parts a pure rich yellow; legs long, slender, and of a pale flesh-colour;
round the eye a narrow ring of yellowish-white; upper mandible pale brown, lower
whitish; eye dark hazel.
"Since writing the above, I have shot two specimens of a bird, which in
every particular agrees with the above, except in having the throat of a dull
buff-colour, instead of a pale ash. Both of these were females; and I have
little doubt but they were of the same species with the present, as their
peculiar activity seemed exactly similar to the males above described."
The males thus described by WILSON, however, I am inclined to think were
young birds in their second plumage.
This species forms a connecting link between Sylvicola and Trichas, having
the long pointed wings of the former, and the general appearance of the latter,
which it resembles, especially in its tail, which is neither emarginate nor
marked with the white spots seen on that of almost all the other Sylvicolae, but
which do not exist in the genus Trichas. Some of the Sylvicolae are, in like
manner, assimilated to Myiodoctes, and others to Vermivora. Of the former may
be mentioned, Sylvicola Auduboni and S. coronata; of the latter,

Wings long, with the first quill longest, and exceeding the first secondary
by eleven-twelfths of an inch; middle toe and claw longer than the tarsus; tail
of moderate length, nearly even, with acuminate feathers. Male olive-green
above; a ring of yellowish-white round the eye; the head, neck, all around, and
part of the breast ash-grey, the sides greyish-green; the rest of the lower
parts bright yellow. Female olive-green above, yellow beneath, the sides of the
neck and a band across the breast tinged with brown.
Male, 5 3/4, 8.

August and September.
